Seven Nozzles, One Print Head – Liqtra launches new LIQTRA FX-7 Pro 3D printer: Technical specifications and pricing

Industrial 3D printer manufacturer Liqtra has launched its latest 3D printer LIQTRA FX-7 Pro with multi-nozzle technology.

The LIQTRA FX-7 Pro, equipped with patent-pending multi-nozzle technology, uses up to seven nozzles in a single print head simultaneously, with each nozzle controlled separately. According to the company, compared to a single or dual nozzle 3D printer, it enhances productivity by up to 300 percent and part strength by up to 37 percent while retaining the same level of geometric detail.

Its operation is managed by the LIQTRA planning software, a multi-nozzle slicer. The software employs artificial intelligence and numerical optimization to determine the optimal part orientation, set process parameters, and plan individual nozzle control. Furthermore, Liqtra GmbH has collaborated with Sanitätshaus Köck & Dengl Orthotreff GmbH and PPprint GmbH to create a leg splint in less than 24 hours, reducing the single nozzle print time of nearly two days by a factor of four.

“The ability of the LIQTRA FX-7 Pro to produce larger medical aids overnight opens up new opportunities for quick and individual patient care,” said Florian Dengl (CEO of Orthotreff).

How does this new launch serve the customers?

LIQTRA multi-nozzle technology uses parallel extrusion throughout the printing process by choosing the optimal active nozzles and extrusion rates for each printing step. The 300 percent productivity increase is especially crucial for meeting ad-hoc printing demands that require medium to large-size parts to be produced in a short period.

Apart from medical aids, the benefits of multi-nozzle 3D printing technology include customized manufacturing aids, jigs and fixtures, and small series production. The LIQTRA FX-7 Pro can process PP and PA (both fiber-reinforced). Liqtra is expanding its selection of processable materials to make its technology available for a broader range of applications.
